To @ZZ whom, t may concern.-

Beitknown that I, CHARLES MCLEOD, manufacturer, of the city of Toronto,in the county of York, in the Province of Ontario, Canada, have inventedcertain new and useful Improvements in SeedingMachines, of which thefollowing is a specification.

My invention relates to improvements in seeding-machines; and the objectof the invention is to devise a simple and effective de vice to stop thecrushing of the grain when it is being sown through the feed-runof thisclass of machine; and it consists, essentially, of a gate provided inthe feed-run intermediate of its length and yieldingly held in position, the remaining portion of the feed-run increasing in size to theexit, and, further, of providing the grain-wheel with a hub attached toor forming part of saine, the periphery of the hub followingsubstantially the inner upper edge of the feed-run and the parts beingconstructed in detail as hereinafter more particularly explained.

Figure l is a'perspective View of a cup and double feed-run, showing theparts involved in my invention. Fig. 2 is a horizontal vsectional planthrough the feed-run and grainwheel on a line with the center of thegate. Fig. 3 is an enlarged perspective view of the cup and run with thegrain-Wheel and shaft removed.

In the drawings like letters of reference indicate corresponding partsin each ligure.

IIeretofore feed-runs in seeding-machines have been a constant source oftrouble on account ot' large grain, such as peas and the like, chokingas they pass through the feedrun. It is with the object of providing ameans to prevent the choking and allow the grain to loosen and passWithout crushing that my invention is particularly designed.

A is one-half of the easing or cup of a double feed-run, and B is thegrain-wheel, which is suitably secured on an axle C, which ex tendsthrough suitable bearings and holes c in the casing. The grain-Wheel Bhas provided, at one side thereof, the disk B', preferably tapered andsecured to the grain-wheel.

A is the feed-run, which is formed in the usual manner at the top with aflaring mouth a and a reduced portion d. The lower portion d2 of thefeed-run is arc-shaped in form and ha-s an outward flare or gradualincrease' in width and depth to a point in proximity to the perimeter ofthe wheel B. (See par- Iticularly Fig.

It will he noticed that the inner perimeter of the wheelB has a seriesof ribs b; but of course this is the usual construction in wheels otthis class.

D isa gate which extends through a rectangular slot a2 midway of thelength of the feed-run. The end ot the gate is rounded off from top tobottom at d. The gate D is provided with a stem d', which extendsthrough a hollow boss A2, attached to or forming part of the casing A ofthe feed-run. The outer end of the stem d is threaded and extendsthrough a nut D', which is provided with a series ofdiametrically-arranged notches d2. The Cotter-pin or key d extendsthrough the notches and the threaded end of the stem CZ.

E is a spiral spring extending between the gate D and the outer end ofthe boss A2.

By driving out the cotter-pin or key cl2 and turning the nut the tensionofthe spiral spring may be increased or diminished, so as to exert agreater or less force upon the gate D.

Although I describe the gate as held in position by the spring E, placedas described, it will of course be understood that I might employvarious other spring devices for holding the gate in position withoutdeparting from the spirit of my invention. The great point is to providethe gate at or near the narrowest part of the feed-run in such a mannerthat when the grain is passing downwardly into the feed-run and binds atthe smallest part the gate will yield on account of the spring and allowthe grain to loosen and pass through wi thout crushing, when the gatewill at once return toits normal position as soon as the jam is brokenaway.

I find in practice that the disk B', which is preferably attached to theside disk of the center weh of the grain-wheel, helps to .a great extentto carry the grain through the wheel and run.

What I claim as my invention is- 1. In a seeding-machine, thecombination IOO with the feed-run and grain-Wheel, of a yieldingly-heldgate located intermediately of the length of the feed-run adapted tohave movement laterally of said Wheel as and for the purpose speciiied.

2. In a seeding-machine, the combination with the feed-run andgrain-wheel, of a gate extending through a slot in the narrowest part ofthe feed-run and projecting into the feedrun and a suitable spring foryieldingly holding the gate in position in the feed-run as and for thepurpose specified.

3. In a seeding-machine, the combination with the feed-run andgrain-Wheel, of a gate extendingthrough a slot in the narroWest part ofthe feed-run and projecting into the feedrun and provided with a stemextending into aholloW boss in the casing ofthe feed-run, and

.a spring for normally pressing the gate into the feed-run as and forthe purpose specified.

4. In a seeding-machine, the combination with the feed-run andgrain-wheel, of a gate extending through a slot in the narrowest part ofthe feed-run and projecting into the feedrun and provided with a stemextending into a holloW boss in the casing of the feed-run, a spiralspring extending between the endof the boss and the gate and nut on thethreaded end of the stem provided with end notches and a cotter-pinextending through the threaded cass end of the pin or stem and thenotches of the nut as and for the purpose specified.

5. In a seeding-machine, the combination With the feedrun andgrain-Wheel, of a yieldingly-held gate located in the narrowest part ofthe feed-run and means for adjusting the gate as and for the purposespecified.

6. In a seeding-machine, the combination with the feed-run andgrain-Wheel, of a yieldingly-held gate located in the narroWest part ofthe feed-run and provided With a rounded upper end and a flat lower sidemeeting at an edge as and for the purpose specified.

'7. A feed-run comprising a casing having a broad mouth at the upper endand a narrow central portion and a flaring arc-shaped discharge end forthe run and a gate adapted to yield laterally situated in the narrowestpa'rt of' the run as and for the purpose specified.

8. The combination with the feed-run, ot14 the grain-wheel and axle, andthe disk located adjacent to the wheel adapted to rotate there- CHARLESMCLEOD.
